What’s Worth Watching: ‘Roots’, ‘Jimmy Kimmel’, ‘Archer’ and more for Thursday, June 2

Roots (9/8c, History, A&E, Lifetime): The final chapter of this powerful miniseries remake focuses on Chicken George (the magnetic René-Jean Page), who returns after 20 years to a new family and a new mission: serving in the Union’s Memphis Colored Battery with Cyrus (T.I.). Time flies as we come full circle with author Alex Haley (Laurence Fishburne). If you’ve missed any of the segments, History, Lifetime and A&E repeat the entire miniseries starting at 2:15 pm/1:15c.

2016 NBA Finals (9/8c, ABC): Coming off record ratings (for TNT), the Golden State Warriors host the Cleveland Cavaliers in Game 1 of the series, a superstar showdown between Stephen Curry and LeBron James. As a curtain-raiser, a special prime-time edition of Jimmy Kimmel Live (8/7c) features Mariah Carey as a special guest.

Archer (10/9c, FX): The seventh-season finale finds L.A.’s most hapless detectives investigating deadly doings on the movie set of Deadly Velvet, which becomes even more deadly upon the discovery of, what else, a dead body.

A Second Look: Repeats of note from CBS’s best sitcoms: On The Big Bang Theory (8/7c), June Squibb is a riot as Sheldon’s (Jim Parsons) beloved Meemaw, whose long-awaited visit turns sour when she shows nothing but contempt for Amy (Mayim Bialik). And on Mom (9/8c), one of the series’ most sobering chapters begins when Bonnie (Allison Janney) and Christy (Anna Faris) befriend a young addict, Jodi (Emily Osment), and try to put her on the path to recovery.
